FRANK ELLISON BEST, OF SEATTLE, WASHINGTON, ASSIGNOB TO FRANK E. BEST, INC., 01 SEATTLE, WASHINGTON, A CORPORATION OF WASHINGTON.

MANUALLY-BELEASABLE SNAP-LATCH-LOCK CORE-HOLDING DEVICE.

Application filed August 21, 1923. Serial No. 658,569.

To all whom it may concern:

Be it known that I, FRANK ELLIsoYs Bns'r,

a citizen of the United States, residing at Seattle, in the count of King and State of IVashington, have invented a certain new and useful Manually-Releasable Snap- Latch-Lock Core-Holding Device, of which the following is a specification.

My invention relates to improvements in 1 looks and an object of my improvement is to rovide a lock having a core arranged to e removably secured in a core case by snap latch means that will snap into an engaged position when the core is inserted into the core case and that may be manually released, whereby, in assembling locks the core may be set up to any de:ired predetermined combination and may then be quickly and easily inserted within the core case where it will be securely locked and held by the snap latch means.

In my prior Patent 1,384,022 issued July 5, 1921, I have shown a lock in which a core is 'removably secured within a core case by key operated locking means, whereas, in the present invention the key operated locking means is dispensed with and snap latch means provided for securing the core in the core case thus making for ease and rapidity in assembling and sim licity in the construction of the lock mec anisr'n.

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings Fig. 1 is a view in perspective showing the exterior of a core case constructed in accordance with my inven- Kl tion.

Fig. 2 is a detached view in perspective of a core adapte to fit into said core case.

Fig. 3 is a view in end elevation of the core and core case. Fig. 4 is a view in horizontal section on broken line 4-4 of Fig. 3.

I Like reference numerals designate like parts throughout the several views.

In the drawing I have shown a core case 5 provided withan internal recess 6 wherein a core 7 is ada ted to fit. For the purpose of this disc osure I have shown the recess 6 and the core 7 both of substantially figure 8 across sectional shape but it will be understood that various other shapes may be employed.

' In accordance with my invention'I provide on opposite sides of the core 7, slots 8 wherein. are disposed snap latch members 9 each secured to the core 7 at one end and having a hook element 10 adjacent -the other end that is arranged to hook over a shoulder 11 formed in the core case, the shoulders 11 shoulders 11. The core case 7 is arranged to be inserted into and secured within a latch housing not shown, in any well known manner.

The core 7 herein shown is of the pin tumbler type having a key plug of the usual form, not shown, and tumbler pins of the usual form, not shown, disposed in perforations 14.

In assembling a lock the perforations 14 in a core 7 may first be filled with tumbler pin sections to form any desired combination and the core 7 may then be nserted full length into the core case 5 so that the hooks l0 snap into engagement with the shoulders 11 andsecurely lock the c re in the core case, after which the core case may be inserted into and secured within any suitable latch housing in such a mann r as to make it impossible to reach and release the snap latch members 9 without first removing the core from the latch housing.

It will be understood that the form and shape of the snap latch members may be varied to any desired extent and that such snap latch members may be secured either to the core member or to the core case member and arranged to engage with the opposite member.

The use of this snap latch means makes it possible to provide a single shear line pin tumbler lock having a removable core that may be quickly and easily locked within the core case and that is easily removable from the core case when the core case is removed from the latch housing with which it is ordinarily associated.

The foregoing description and accompanying drawings clearly disclose one operative embodiment of the invention but it will be understood that various changes in the device-may be resorted to within the 'scope and spirit of the following claims,

I claim:

1. In a lock a core case, a core removable from said core case andsnap latch means arranged to be released without the use. of a key for locking said core in said core case.

2. In a look, a core case, a core removable from said core case and snap means for locking said core in said core case said snap means being releasable manually without the use of a key from the, exterior of said core case.

3. In a look, a core case arranged to be inserted in a lock housing, a core arranged to be inserted in said core case, snap latch means-for securing said core in said core case and means accessible only when said core case is removed from said lock housing for releasing said snap latch means.

4. In a look, a core case having a recess therein, a core arranged to fit within said recess, catch members arranged to snap into an engaged position when said core is inserted into said core case, and means afiording access to said catch members whereby they may be released.

5. In a lock a core case having recesses provided in the inner end, a lock core having grooves along the sides, resilient snap latch members'secured to the core and extending along the grooves, and hooks on the ends of said snap latch members arranged to engage the core case and posltioned in the recesses on the'inner end of said core case. The foregoing specification signed at Seattle, Washington, this 8th day of August, 1923.
